The system is already unstable due to the rampart growth of wealth inequality, especially after covid, disproportionately affecting the purchasing power and CoL of the working class, while those with assets have seen their wealth ballon. All orchestrated by EU politicians and the ECB currency inflation policies and and allocation towards banks and corporations who spent it during covid on assets and stock buybacks and left the working class footing the bill with inflation and mass layoffs years later.
The EU elites are already worried about how they can manage this bottled anger of the working class, which is why you see more and more draconical EU "chat control" and "speech control" laws trying to get passed. Pointing the peasants to vent their anger towards Russia as the scapegoat, for the fiscal irresponsibility of the EU elites that lead to the current wealth disparity, is a good way for the EU elites to avoid the angry mob.
After all, most of the wealthy European elites and nobles didn't lose their wealth after WW1 and WW2 even though millions of peasants died.
